To all whom, it may concern:

Be it known that we, RALPH L. HALL and THOMAS C. MARTIN, citizens of the United States, residing at Ualdand, in the county of Alameda and State of California, have irlvented certain new and useful Improvements in Seam-Ironing Machines, of which the following is a specication. y

This invention relates to a machine for ironing the seams of turn-down collars.

The object of the invention is to provide a machine i of this character which shall be vcheap and simple in construction and operation. I

In the accompanying drawings, Figure 1 is a plan view of the machine. Fig, 2 is a front view thereof. Fig, 3 is a broken vertical section of a portion ofthe machine.

Referring to the drawings, 1 represents a main driving-shaft sup orted in front and rear bearings 2, depen ing from a table 3, said shaft being driven by a belt 4 and pulley 5 from any suitable source of power. Upon said shaft is secured a beveled pinion 6, which meshes with a beveled gear-wheel 7 on avertical shaft 8, saidwheelhavinofformed therewith two small intermediate gear-wheels 1() 11 on vertical shafts`12 131 said wheels meshing in turn with large gear-wheels 14 15 on vertical shafts 17 16, upon which shafts are also mounted gear-wheels 19 18, which mesh With gear-wheels 20 21 upon vertical shafts 23 22. Said vertical shafts thus forni two pairs-a pair of shafts 16 22 at the feed end of the machine and a pair 17 23 at the delivery end thereof. The first pair of shafts carry feed-rollers 24,`and the second pair carry delivery-rollers 25, all having rubber-coronal surfaces 26. Upon brackets 27 are supported guide-plates 28, between which is supported a vertical curved shaper-plate 29, supported upon the table 3 by a llange 5!) and extending beneath the groove. 42 oll the iron roller 31, hereinafter described, and the collar to be operated upon is placed upon the upper edge of said shaper-plate. When the collar is placed on the shaper-plate 2) and is passed between said guide-plates 28, its advancingedge passes between the pair ol'v rollers 24, which, byreason of the nlotion imparted thereto from the main driving-shaft,

feed said collar forward still supported upon Y the edge ol' the shalper-plate. The collar thus moving on the e( ge ol the sharper-plaie 2) passes between a second pair of guide-plates a gear-wheel 9, which meshes with 30, supported by posts 60, secured by flanges 61 to the table, one on each side ofthe Shaperplate 29, and is thus fed underneath an ironing-roller 31, mounted upon a shaft 32 in a bearingA 33, said bearing being supported by trunnions 34 between standards 35, secured upon the table. Said shaft 32 is driven by means of a sprocket-Wheel 36 thereon, a sprocket-chain 37, and al sprocket-Wheel 38 upon the main shaft 1. Said roller 31 is formed with a cylindrical shell constituting a l heating-chamber 39, into which extends a' gaspripe 40, controlled by a valve 41, the flame om the'llurner of said gas-pi e heating said roller to produce the ironing e ect. The circumference of said roller, near its extreme edge, is formed with a circular groove 42, which rests upon the collar and shapes the same.

In order to render the ironing-roller selfadjusting in reo-ard to its pressure, there is secured to the fiat under side of the bearing 33 for the shaft 32 a plate 43, through the other end of which passes a rod 44, rigidly secured at its lower end to the table and screwthreaded at the upper end and having a thumb-nut 45, screwed on the upper end and bearing down upon the free end of the plate, ressing it against a coiled spring 46, the ower endof which is supported by a crosspin 47 in the rod; An upward pressure upon the ironing-roller will evidently cause a downward movement of the end of the plate, which will be resisted by the coiled spring. Said coiled spring thus provides a resilient support for the ironing-roller, opposing. its upward movement.

The upper edges of the guide-plates 3() are formed with. concave recesses 48 to corre- `spond with the circular forni of said roller and iminediatelythereuiul'er. Upon assingfrom between the second pair of gui( e-plates the collar passes between. the delivery-rollers 25, which carry the collar therethrough against the surface ol" a bending-roller 49, which is upon a vertical shaft 50, driven by a gear 53, meshing with the gear-wheel 14 upon the shal't 17. When the collar irnpinges against the surface of this lninding-roller, it is caused to be dellected and curved to the proper shape.

In order to hold the collar down onto the sharper-plate, there is provided a roller 51, the axle of which nieves vertically in slots 52 in the up )er ends of the Abrackets 27. slots allow a vertical movement of the roller These IOO IIO

-t'o permit it to rise when the end ofthe collar in Which the buttonhole is formed passes thereunder. In some collars this end is given an elevation above the plane of the main portion of the collar, and it is to revent undue pressure upon the elevated e ge of the terminal portion of the collar thatthese slots the space between the guide-plates,` means for heating said ironing-roller, a Shaper-plate for sup orting a collar and means for feeding y said co1 ar between vthe guide-plates, substan7 tially as described..

2. In an apparatus of the character described, the combination of a pair of'guideplates, an ironing-roller supported thcreover aving an annular groove immediately over the 'space between the guide-plates, a resili- -ent support forsaid'roning-rollervresisting its upward movement, means for heating said ironing-roller, a Shaper-plate for supporting aA collar and means for feeding said collar' between the guideplates, substantially as described.

3. In an apparatus of the character described, the combination of a pair of guidelates, an ironing-roller supported thereover having an annulargroove immediately over the space between the guidelates, means independent of a movement-o the collar for rotating said ironin -rol1er, means for heating said ironin ro ler, a'shaper-plate for sup orting a colar and means for vfeeding saidp collar between the guide-plates, substantially as described.

In witness whereof we have hereunto set our hands in the presence of two subscribing REGINA A. ERwIN.
